My sister got a Brazilian butt lift ending of February and after three weeks she started to form a lump on her butt & hip that was hot to the touch that then turned white, fluid then started coming out of it & she has now been in the hospital for 4 days now. I am getting a BBL in June & watching her recovery has been disheartening . I want to prevent getting an infection as well. What pre-operative precautions can I take ? Was the infection cause by her doctor or a mistake she may have made?
